ideally after declaring the function.

CanCover is not transitive. The counter example are Nodes A,B,C such
that CanCover(A, B) and CanCover(B,C) and B is pure. In this case the
effect level of A and B might differ.
This CL adds a missing CanCover check to a case of shift reduction where
we assumed transitivity.
